Sometimes it’s a little difficult to explain why so many people find anal sex uncomfortable.
The “bum” is made up of a number of critical components chiefly for the purposes of anal, the sphincters (anus) and the rectums.Though not visible in this shot the sphincters are the gateway with the outer (pelvic floor) part being under conscious control and the inner forming part of the reflexive nervous system. Teaching folk to breathe deeply, use lube and relax the outer is as far as most anal sexstuction gets.
The rectum is made up of two parts which for our purposes we’ll call the upper and lower rectum. The lower rectum is a single chamber of the other side of the anus and although elastic anything too long will prod the sides and make life uncomfortable.
The body contains an upper rectum that acts as a transitory store for faeces on the way down from the colon. In a fit and anally healthy human faeces moving from the colon into the upper colon should trigger a bowel movement and therefore willtypically be empty. Many folk attempt to deny their bodies and BM resulting in fullness here and eventually to constipation.
Interestingly the sensations here are driven by the same part of the nervous system as the clitoris/head of the penis.
The trick with anal is with whatever is inserted to fin this upper rectum, clearly visible in this picture as a tube passing in from the lower rectum. Get the object of your attentions into here and there’s about 10 inches of tube in which the most amazing sensations can be reached.
Normally this tube, the access to the upper rectum is pushed back against the spine so feel backwards, away from the vagina for access.

Okay.. Is it weird that I’m looking at this in fascination because of a scientific reason and not out of sexual arousal?
